species, least of all to any of Mr. Schaus' new species, of all of 

 which I have seen cotypes. The name is a manuscript one of the 

 late Henry Edwards. 



Dark brown, the fore wings as usual, but the dots yellow, gen 

 erally very large and often an additional linear yellow streak in 

 the center of the cell in the male. Hind wings uniform chocolate 

 brown. The species is rather small, dark, the red shades not 

 developed, but the yellow unusually prominent. Expanse, male 

 28 to 32 mm., female 40 to 45 mm. Twenty-six males, three 

 females from Mr. Schaus, presumably collected by him in Jalapa, 

 Mexico. One male from Franck collection labelled ci Mex.,"not 

 unlikely from the same catch. U. S* Nat. Mus., type No. 4432. 

 Genitalia shown in fig. 5. 



S. stimulea Clem. 



Our common moth from the often described "saddle-back" 

 caterpillar. Genitalia shown in fig. 2.

S. fusca Stoll. 



Again a single female is figured. This is rather uniform and 

 a light brown with the three subapical dots present, large ; ex 

 panse 54 mm. I have elsewhere, following Moschler, identified 

 this with trimacula and boncerensis, and I see no reason to 

 change. The figure might apply to one of several species, but as 

 it can not be told which was intended, I would hereby recognize 

 Moschler's restriction of it to the present form. Moschler gives 

 also as a synonym ? quercinia Men., but I know no description 

 bearing the name. In rufescens, described from " country un 

 known," Walker defines a form which I cannot distinguish from 

 those fusca that lack the yellow dots. Genitalia fig. i.

6". extensa Schaus. 



Mr. Schaus describes male and female, and the latter is figured 

 in the Biologia. From these alone I should not know what was 

 intended, but I have specimens from Mr. Schaus, not labelled, 

 but presumably collected by himself in Jalapa, Mexico. They 

 agree exactly with description and figure, and the male genitalia
